Hi all, hope your all well

Looking for some support or guidance please. 
I've always had a beauty spot/ mole on the back of my leg on my calf. Few months ago I noticed it was getting quite big! Recently I noticed it was scabby! And just weird looking after being perfectly round and small.

anyway on 6th July I called my doctor and he asked me for some photos. After seeing the photos he referred me straight away to a specialist on a two week priority appointment (NHS).i recieved a call the next day from the specialist and had also seen the photos. They asked me questions and then told me they will remove it to be on the safe side but due to Covid and no hospital appointments they can check it!and they can't confirm when a hospital appointment will be available. 
In the meantime I thought I would go private just to get it checked by a dermatologist! I managed to get a appointment on 10th July and she checked all my body and the mole in question and said that she thinks it's melanoma! She was quite surprised as I'm of Pakistan origin! I said to her that what percentage is it that it's not melanoma and she said it's highly likely that it is rather then it isn't! I didn't know what to think at that point I was wearing a face mask and I was literally dripping with sweat and confused and scared to say the least! 
she advised me that it's better to get it removed on the NHS as if I need further treatment I will already be in there system! But I should get it removed in the next 14 days! 
I then began calling the appointment line daily and managed to get a appointment on 23rd July and got it removed! I'm currently now waiting for my biopsy results! 
has anyone been through something similar??? 
if the dermatologist has told me she thinks it's highly likely it is melanoma then has anyone had Experiance that what they where told it did actually turn out to be that? 
I'm in week 2 now of waiting for results! They told me 2-3 weeks! 
is it the case that the longer I wait it actually means it is something? 

thank you in advance for any advice.
